Release Notes v7.1.00What's New
Support for HP XP P9000 and HP XP P9500 disk arrays.
The new metric ST_DISK was added to the STOGLB dataset to expose the total number ofused disks.
Changes and ImprovementsVolumes Monitoring configuration has been improved to be more user-friendly. A singleoption is now available to enable/disable volumes monitoring and volumes import.
The SA_CONTAINS_LUN and SP_CONTAINS_LUN relations have been respectively replacedby SA_CONTAINS_VOLUME and SP_CONTAINS_VOLUME.
The computation method for the ST_SYSTEM_SUBSCRIBED_CAPACITY andST_POOL_SUBSCRIBED_CAPACITY metrics has been modified and is now the sum of the hostvisible capacity of the mapped volume.
Fixed IssuesAn error occurred when deploying the ETL package v7.0.00 with BMC TrueSight CO 10.3 on anOracle database.
The ST_CONSUMED_CAPACITY and ST_AVAILABLE_FOR_STORAGE_POOLS metrics did notexpose the actual value for HP XP P9500 disk arrays.
Connector's loading has been improved to prevent failures when local store files arecorrupted.

Customizing Volumes MonitoringDiscovering volumes and collecting their performance metrics are resource-intensive actionsthat can create extra workload on the system. To reduce the system resource consumption,administrators can disable or enable the volumes monitoring at will and fine-tune the creation ofvolume entities into the BMC TrueSight Capacity Optimization environment.

To customize volumes monitoring:1. Edit the Hitachi Device Manager ETL for BMC TrueSight Capacity Optimization Run
Configuration.
2. Expand the ETL additional settings menu.
Customizing Volumes Monitoring
3. From the Volumes pull-down list, select one of the following options:
Option Result
Disabled Volumes are not discovered.Volumes-related metrics are not loaded in the console.
Use this conf iguration if the number of volumes to manage signif icantly slows downthe system performance. Disabling the volumes monitoring prevents the discovery ofany volumes and consequently does not allow the ETL to collect, save or process theirdata. Note that the calculation of metrics for other sources may be impacted (see tablebelow and reference guide).
Collected formetriccomputation(Default)
All volumes are discovered and their metrics are collected and processed.Volumes-related metrics are not loaded in the console.
Use this conf iguration if you wish to collect and process volume-related metrics withoutloading this information in the console. The collected data will however be used tocalculate metrics for other sources, when required. This will reduce the resourceconsumption of your system.
Collected andImported
All volumes are discovered and their metrics are collected and processed.Volumes-related metrics are saved in the database, processed and loaded in theconsole.
Use this conf iguration if your system is powerful enough to manage all the volumes tomonitor.

Introduction
The Sentry Software support team may ask you to provide log files to better diagnose the natureof a problem. You can either choose to:
Collect logs for a specific ETL (recommended)
Grab all logs
Please note that both methods require to:
Set the log level to 10 - Verbose
Wait for the connector to collect data (usually 1 hour). On some rare occasions, a highlydetailed collect (discovery) is required. In that case, the scheduler service will need to berestarted.
